WINDOW-BLIND.

SPECIFICATION forming part of Letters Patent No. 465,395, dated December15, 1891, Application filed March 21, 1890. Renewed October 30, 1891.Serial No. 410,388. (No model.)

To all whom. it may concern:

Be it known that we, EDWARD STOEPPEL- WERTH and CHARLES H. KNEFELKAMP,o'f St. Louis, Missouri, have jointly made a new and useful Improvementin Vindow-Blinds, of which the following is a full, clear, and exactdescription.

The improvement relates partly to the journaling of the blind-slats andpartly to the ro means for adjusting the blind-slats, substantially asis hereinafter set forth and claimed,

aided by the annexed drawings, making part of this specification, inwhich- Figure 1 is a side elevation of theimproved r 5 blind; Fig. 2, avertical section on the line 2 2 of Fig. 1; Fig. 3, a horizontal sectionof the blind, the slat being partly in plan and partly in horizontalsection; Fig. 4, a View in perspective showing an end of one of theslats;

zo and Fig. 5 an elevation of one of the metal strips which are let`into the stiles of the blind. The last three views are upon an enlargedscale.

The same letters of reference Adenote the same parts.

The blind A is ot` the usual construction, saving as it is modified orsupplemented by the improvement under consideration.

D B B represent the blind-Stiles; O, the bottom rail; D, the top rail;E, the middle rail, n and F F the slats. The slats at each end thereofare held in and covered byasocket G, and the socket in turn is providedwith al journal H, which projects into a suitable re- 3 5 cess in thestile B. The journal passes first through a metal strip I, which is letinto the stile, substantially as shown more distinctly in Fig. 3. Thejournal may be made in one piece with the socket, or a separate piecese- The slat, socket, and journal turn as one part in the strip I andstile. By this'means the slats are strengthened and protected at theirends, and the slatjournals are met-al parts journaled in metal bearings.The slats can bevsnugly fitted to the stiles, and the weather is lessliable to interfere with the proper working of the slats than when theblind-slats and stiles are all wood, as heretofore constructed.

5o The other feature of the improved blind consists, mainly, in thenotched rod J, which is employed to adjust the slats, and by which meansthe slats can be turned in their bearings without being required to bejointed to the rod, as blind-slats heretofore have been. The rod andslats are relatively adjusted to cause the slat edges f and therod-notches j to interact, so that bymoving the rod J upward anddownward the slats can be rotated in their respective bearings in thestiles and be turned upward 'and downward and openedand closed, asdesired.

A desirable means for holding the rod in engagement with the slats andenabling the rod to be used to operate the slats, as described, are thelinks jj, which at one end are jointed to the rod and at the other endto the blind-rails, respectively, and substantially as shown. We do not,however, desire to be restricted to this means, as the rod can beotherwise held in place. The rod J is preferably of metal, and itpreferably is arranged near the stile, and it preferably is arranged tobear upon those parts of the slats which are covered by the sockets G.There may be more than one rod J, as when it is desired to operate theslats in the lower part of the blind independently of the slats in theupper part of the blind, and in'such case the rods maybe arranged,respectively, toward the Stiles B B', as shown. The blind-rails may begrooved, as at b, to provide for the movement of the rods when shapedand arranged as shown. The strips I may be held in their places in thestiles by any suitable means-as, for instance, by the slats, whichprevent the strips from becoming detached from the stiles.

The perforations in the strips I to receive the Slat-journals are shownat t', Fig. 5.

The strips I serve the purpose of re-enforcing the bearingrecesses inthe stiles, and the journals H, while shown secured to the sockets,would be more easily made integral therewith, and the socket would bethereby rendered stronger. Y

The rod J has concave notches and convex projections between thenotches, and the rounded edges of the sockets G rest in said notches andare lifted by said projections, so roo that as there are no corners oranglers there will be no noise or jar when opened and closed.

XV e claiml. In a blind, the combination, with the recessed stiles, theslats, and the sockets G, secured upon the ends of the slats andprovided with the central journals H, of the rod J, provided withnotches to receive the edges of the corresponding sockets and liftingprojections between said notches, and means, substantially as described,wherebj7 the upper and lower ends of said rod are connected to the frameof the blind, substantially as specified.

2. Inablind, the combination, with the slats and the metal socketssecured over the ends the slats are.
